The risk of ‘liar loans’: Can overstretched borrowers cope with higher interest rates?

“While it’s sad that people feel the need to mislead or lie on their loan applications, we do not take our customers at their word, and actually the law requires that we do not,” Elliott said.

Even so, others who are more pessimistic about the property market, such as Digital Finance Analytics founder Martin North, believe the ongoing debate about “liar loans” highlights the risk that some people have stretched themselves too far to buy property.

“Is it a liar loan, or is it being encouraged by mortgage brokers, for example, to present your information in a particular way because they know how to get it through the system?” North says.

North, who has long had concerns about the high level of household debt, worries that rate hikes could be part of a “perfect storm” slowly brewing in housing, alongside rising cost of living, falling house prices, and stagnant income growth. North says his monthly surveys of 4500 people show more than a third have problems with their cashflow, though he also says it will take a couple of years for the full extent of mortgage stress to emerge.

Many market observers also believe high household indebtedness will mean the RBA needs to tread carefully in raising rates.

Hempton, of Bronte Capital, puts it this way: “The question is how far can the Reserve Bank push up interest rates before they cause real pain in this economy? And I think the answer is not very far.”

As things stand, the number of people getting into trouble with their home loan repayments is very low.

ANZ’s Elliott described his bank’s credit quality as “amazingly benign” on Wednesday, saying 0.7 per cent of its borrowers were behind on their home loan, compared with 1 per cent normally.

An analyst at S&P Global Ratings, Erin Kitson, says there are a number of “mitigating factors” that temper the risks created by rising rates and high housing debt.

Unemployment is regarded as the most important driver of mortgage defaults, yet it is at its lowest level in decades. Banks have reduced interest-only lending, and loans to people with skinny deposits. Households have also amassed a whopping $240 billion in savings in the pandemic, which may act as a cushion as interest costs creep up.

As for “liar loans”, Kitson points to digital advances that have made it easier for banks to check if customers’ applications are factual, by comparing their claims with financial data. “It’s hard to hide that now, because you can see it in the transaction history of borrowers,” she says.

Many in the financial establishment are not convinced there will be a major wave of bad home loans. But few predicted inflation and interest rates would be rising this sharply either.
